Apply separate color maps on same plot.

Hello, I am trying to apply 2 color maps on the same plot. I have found that the following command applies two evenly distributed color maps over the total range of all the plotted figures.

{colormap([jet(64); jet(64)]);}

Problem is, my figures ranges are are not evenly distributed , nor do they cover the whole value range. The first figure has value from 1-9, the second varies from 250-300. I somehow need to skew the two evenly distributed colors bars so they range from 0-9 and from 250-300.

Please help!
